Thank you contacting Syncfusion support.
On analyzing the provided information and mentioned requirement “Customizing Step view independently” is not feasible in SfStepProgressbar. The behavior of SfStepProgressbar will be as follows.
1. There will be only one in-progress state in step view.
2. Steps before in-progress state will be completed.
3. Steps after in-progress state will be Not started.
So, the requested requirement can’t be achieved using SfStepProgessBar. Kindly, let us know if you require any further assistance.
